Why does the car shake when running at high speed?
1 Answers
The reasons for car shaking at high speed are: 1. Inaccurate front wheel alignment angle, excessive toe-in; 2. Low front tire pressure or unbalanced tires due to repairs; 3. Deformed front wheel rims or unequal number of tire bolts; 4. Loose installation of transmission system components. Solutions for body shaking include: 1. First lift the drive axle, place safety blocks for the front wheels, start the engine and gradually shift to higher gears to make the drive wheels reach the final test vibration speed. If both the body and steering wheel shake at this time, it is vibration caused by the transmission system; 2. Check whether the front wheel alignment angles and toe-in meet the requirements, and adjust if inaccurate; 3. Lift the front axle and test rotate the wheels to check the static balance of the wheels and whether the tires are excessively deformed. If necessary, replace with good wheels for comparison tests.
